- normal script execution shares its context with modules now (like on Node.js)
- expose a "global" symbol that references the global scope (like on Node.js)
- modules may return arbitrary values (not just objects; now like on Node.js)
- pick up exports from "module.exports" also (like on Node.js)
- handle exceptions thrown in module loader/normaliser like in other PHP scopes called from JS
(i.e. by default terminate execution, optionally propagate to JS side)

Correctly initialize V8's ICU component
- path to libv8 library is now baked into the library to find icudtl.dat file
- if icudtl.dat file is moved after compile time, set v8js.icudtl_dat_path php.ini variable

This release also merges in new features from V8Js 0.4.0, namely
- Improve -Wno-c++11-narrowing/-Wno-narrowing flag detection (clang/gcc5 support)
- Added ability to set properties on V8Function
- CommonJS modules now have access to V8Js' var_dump function
- V8JsScriptExtensions now reference the normalised module id (instead of just "require")
- fatal PHP errors triggered in setModuleLoader callback are now handled gracefully
- setModuleLoader callback is now allowed to return an empty string as source of module
- V8Js' internal module path normalisation may now be overrode using setModuleNormaliser
